Aucbvax.4480 fa.unix-wizards utzoo!decvax!ucbvax!unix-wizards Thu Oct 15 23:47:39 1981 double setuid programs and accounting >From cbosgd!mark@Berkeley Thu Oct 15 21:17:03 1981 In reply to Dale DeJager's note about accounting:

I claim that the real uid is no good for accounting anyway, since the UNIX philosophy is to let one user start a daemon which does work spooled by many. The uucp and lpr deamons work this way - you could be charged for a good deal of work that was spooled by someone else. I would appreciate hearing from sites that really do accounting - to what extent do you depend on the real uid, and what do you do about uucp and lpr? What sites out there would object to allowing setuid(geteuid()) on accounting or other grounds?

mknod needs to be protected to prevent people from making nonstandard directory structures (with funny things in . and ..) and read-allowed versions of special devices, protected files, etc.
